Özet
Bu çalışmada, Umbrina cirrosa (Linnaeus, 1758) ve Argyrosomus regius (Asso, 1801)'un akuakültür şartlarında suni döllenme yoluyla çaprazlanmasıyla elde edilen hibrit bireylerinin bazı morfometrik özellikleri ve boy-ağırlık ilişkileri incelenmiştir. 39 bireyde boy, ağırlık ve kondisyon faktörü değerleri sırasıyla 26,12 - 48,67 mm, 0, 7 - 0, 99 g, 0,81- 1,09 arasındadır. Boy-ağırlık ilişkisi, 0, 000009 * TL 3.006 r = 0, 99 olarak hesaplanmıştır. Regresyon analizi sonuçlarına göre bireyler b değerine göre izometrik büyüme (b=3) göstermiştir. Biyotrik analizler sonunda örnekler arasında 10 morfometrik ölçüm içinde en önemli farklılık üst çene-pektoral yüzgeç (MPL) arasında (P<0, 05) olduğu tespit edilmiştir. Buna karşın en yüksek korelasyon baş boyu (HL) ve total boy (TL) arasındadır (P< 0,05). Sonuç olarak, hibrit balıkların vücut yüksekliği ebeveynlerinden nispeten düşük, Akdeniz populasyonlarına göre daha kısa ve büyüme değerlerinin doğal populasyonlarla eşittir
In this study, length-weight relations and some morphometric characteristics of hybrid juveniles obtained by crossing of Umbrina cirrosa (Linnaeus, 1758) and Argyrosomus regius (Asso, 1801) via artificial fertilization under aquaculture conditions were investigated. Lengths, weights and condition factors of 39 hybrid juvenile specimen varied between 26.12 and 48.67 mm, 0.7 and 0.99 g, 0.81 and 1.09 respectively. Length-weight relationship (W) was calculated (0.000009 * TL3.006 r= 0.99). Individuals have shown isometric growth (b=3) according to the results of regression analyze by b value. All 10 morphometric measurements presented significant differences between the examined species in this study at the end of biometrical analyses except distance of maxilla and pectoral fin (MPL) (P<0.05). However, the strongest correlation was found between head length (HL) and total length (TL) (P<0.05). As a result, body height of hybrid fish was respectively lower than the parent species and length was shorter compared to Mediterranean populations indicating growth values were equal to those of natural populations
